In a nutshell well said. Other teams have developed, the Phoenix have not. Totori and Smith are not worthy of import slots at this level. RH has made too many of these mediocre signings.
The only thing left for this season is to give serious game time to Boxall, Hogg and Lindsay to augment the development of Fenton and Boyd. That at least will be a positive for the future of the franchise.
Have a look at how Paul Marshall has Waitakere playing in the ASBP. He could be a good choice for a new home-grown coach for the Phoenix next season. He has a good attacking mindset.
I do think that if the season is 'over' in terms of the play offs, then Boxall, Hogg and Lindsay should be played to up their game time/experience and see if they are worth keeping for next year (Obvious Boxall is already). It would be pointless to keep trotting out Lia, Sigmund and Lochhead in that instance..
